ABSTRACT

Objective To study the imaging findings and patholoical characterizes of chondromyxoid fibroma in order to improve its differential diagnosis.Methods 8 cases with chondromyxoid fibroma had all proceeded x-ray checked before operation. Of these cases , 4 cases were examed by CT scan .All cases were confirmed by operation and pathology. The imaging findings and pathological characterizes were analysed.Results The lesions located at metaphysis of long bone and presented as a round or elliptic transparent area which were consistent with long axis of involved bone. There were osseous crests inside the lesions and sclerosis bone around the lesions. The density of lesions was homogeneous and CT numbers were about 26 HU. On histopathology,lesions presented grey. Lobular and some what transparent . In the center of lesions there were a lots of mucus and stellate cells. The lesions were surrounded by hyperplastic area including multinuclear giant cell and chondroblast fibroblast. Conclusion chondromyxoid fibroma has characterizes on imagiology and pathology , but it has often been misdiagnosed.
